This miraculously fixes the issue were the StoredQueryParameters
have not been validated.

Whilst debugging the code, I realised that the "Extract Stored Query Mechanism"
might be enhanced.

Currently this happens:

---Extract Stored Query---
name:
value:
type:
--------------------------
---Extract Stored Query---
name: CRS
value: asd
type: CRS
--------------------------
AddAttr: set CRS to asd
the type is (wasnt set): CRS
The given type is: string
Settiong type to: string
---Extract Stored Query---
name: CRS
value: asd
type: string
--------------------------
